The box should only be used to get the headphones to the customer without the product breaking on the way.

Saves environment anyways and it can't be used to justify costs. Those that really need to carry their headphones around can buy one separately. Though it's pretty nice that my DT1990 came with a carrying case but everyone doesn't need one so it should be a separate product as well. So wasteful.

Although we as customers might still just be getting less for the same price. No idea how sennheiser or any of the other competitors lower their prices in long term if they stop including nice boxes or carrying cases
